To all whom t may concern:

Be it known that LCHEssMAN W THoRNE,a citizen of the United States, residing at Greenport, in the county of Suffolk and State of New York, have invented certain new and useful Improvements in Ash-Ejectors g and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The objects of this invention are to facilitate the removal of ashes from the furnaceroom, more particularly of steam-yachts or other vessels; to prevent the ashes from clogging within the passages of the ejector, between the converging Walls thereof, by bridging the said passages, and thus requiring the use of a poker or other implement to break the arch and permit a proper gravitation of the ashes into contact with the ej eotin g stream of Water, steam, or other iuid by which the ashes are carried away, and to obtain other advantages and results, some of which may be referred to hereinafter in connection with the description of the'working parts.

The invention consists in the improved ashejector and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure l is a front elevation, and Fig. 2 is a plan, of the improved ejector. Fig. 3 is a section taken through vline x of Fig. 2; and Figs. 4, 5, and (i are sections taken on lines x2 x3, respectively, of Fig. 3.

Heretoforeit has been more or less common to eject ashes from a hopper by means of a water-jet; but such devices have been objectionable because of the liability of the ashes to clog in the hopper and require more or less hand manipulation to secure a final ejection. By means of my improvements I prevent such clogging, and in practice no such objection is experienced.

In said drawings, a indicates a hopper having a flaring or funnel-like upward extension open at its upper end to the furnace-room and provided with a cover b, by which the opening may be securely closed in any suitablemanne'r. At the lower small end or bottom of said hopper the same receives the Vhydraulic or fluid ejector c', the nozzlefcl of which enters through a perforation in the bottom of the hopper, as shown in Fig. 3. In

connection with said hopper, preferably integral therewith, is' formed a tubular eXtension e, which lies at an angle to the axial line of the hopper in line with the nozzle d, so that the water issuing from said nozzle will .pass

upward direct-ly through said extension and with it force the ashes outward from the hopper, as is common. v

To prevent the ashes becoming clogged in the hopper by bridging the converging walls thereof, I have provided, in connection with the main passage f of the ejector, a supplemental or branch water passage or duct g, adapted to receive a part of the water-supply from the water-feed pipe h and direct it into' a side passage or duct g formed in the walls of the hopper or upon said walls and leading to a point about half-way up the sides of the hopper, where said duct d is turned inward and opens through the wall `of the hopper into the hopper, as at j. Said extremity of the supplemental passage is preferablyturned downward, as shown in Fig. 3, and over the end of said passage, where it opens into the hopper, I prefer to employ a deflecting-plate 7c. Said delecting-plate is attached to the inner wall of the hopper and hangs down over the mouth of the supplemental passage g' at a little distance therefrom. The Water issuing from the supplemental passage therefore strikes the deilecting-plate k and is directed to the right and left and downward around the inside of the hopper, 4forming a revolving sheet of water, which follows the walls of the hopper between said walls and the ashes or other contents of the hopper. This flattened stream bein g under more or less pressure and possessing considerable force effectually undermines the contents of the hopper and renders it impossible for the bottom passage of the hopper to become clogged with any body smaller than thesaid outlet.

At an intermediate point between the ej ector c and the outlet j the hopper is provided IOO Y ashes are thrown into the hopper.

with a valve Z, adapted to close communication or out oi iiowthrongh the supplemental passage when desirable. This valveZ may be of any ordinary construction.

In operating the device the water is simply turned on through the passages fand g gj by means of a cock or valve (not shown) in the feed-pipeh, the cover b is opened, and the The water flowing downward in said hopper from the passage j carries with it the ashes to the bottom, where they are brought under the influence of the main ejecting -stream and are forced thereby through the tube e.

By my improved construction there is no danger of the contents of the hopper becoming bridged, and consequently no time is lost in poking or ramming down the contents to insure their proper removal. tents are carried rapidly and surel y away from the hopper,and in practice I am enabled to dispose of about twice the quantity of ashes in a given time that could be handled with out the auxiliary stream.

I am aware that various minor deviations may be made from the exact construction shown without departing from the spirit and scope of the invention, and I do not wish to be understood as limiting myself by the positive descriptive terms employed excepting as the state of the art may require.

Having thus described the invention, what I claim as new is-L y l. The improved ash-ejector comprising a hopper, having an extension and a duct conveying water into the upper part of said hopper, and a fluid-ejecting nozzle in open communication with said extension and duct, substantially as set forth.

The said con-` 2. The improved ash-ejeetor, comprising a hopper having anextension e, in connection with the bottom thereof, a duct g', opening into the hopper and adapted to direct the fluid toward the bottom of the hopper and a fluidejector having a passage leading directly into the hopper at the bottom and a passage connecting with said duct, substantially as set forth.

3. An ash-ejector comprising a hopper having an outlet-passage nearits bottom,an ejecting-nozzle opening into the lower part of said hopper in line with the said outlet, said nozzle having a branch passage leading upward and opening into the upper part of the hopper, substantially as set forth.

4. An ash-ej ector comprising a hopper having an outlet near its bottom, an ejecting-nozzle having a main passage leading into the lower part of the hopper and a branch passage leading upward and opening downwardly through the side wall of the hopper, and a valve for regulating the flow through said branch passage, substantially as set forth.

5. An ash-ejector comprising a hopper to receive the ashes, said hopper having an outlet near the bottom, a nozzle having a main duct entering the lower part of the hopper and a branch duct entering the upper part of the hopper, and a deilecting-plate arranged over the opening of said branch duct into the hopper, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 1st day of May, 1899.
